Hello,

I'm trying to use a CheckButton called case0, all this code is included in a class (hence the self prefixes).

My problem is that the line "self.checkVar.get()" does'nt return the state of the checkbutton.

It returns 0 whatever I do (even if I change the on/off values of the checkbutton).

def pop_up_search(self):
        self.fen1=Tk()
        
        self.but3=Button(self.fen1,text='Annuler', command=self.fen1.quit)
        self.but3.grid(column=3 , row=2 )
        
        self.but4=Button(self.fen1,text='Search', command= self.search)
        self.but4.grid(column=0 , row=2 )
        
        self.entry0=Entry(self.fen1,text='Nom du site')
        self.entry0.grid(column=1 , row=0 , columnspan=2 )
        
        self.text0=Label(self.fen1,text='Nom du site')
        self.text0.grid(column=0, row=0 )
        
        self.checkVar=IntVar()
        self.case0=Checkbutton(self.fen1, text='Tout voir ?', variable=self.checkVar, onvalue=1, offvalue=0)
        self.case0.grid(column=1,row=1)
        
        
        self.fen1.mainloop()
        self.fen1.destroy()
        
    def search(self):
        self.nom=self.entry0.get()
        if self.nom=='' and checkVar.get() ==0:
            self.text1=Label(self.fen1,text='Remplir le nom du site')
            self.text1.grid(column=1 , row=2 , columnspan=2)
            
            return
        
        self.commit_search(self.nom)
        self.fen1.quit()

Put variable self.checkVar in __init__ method

Bonjour,

Déplacement vers un forum plus approprié

Le sujet est déplacé de la section Langage Python vers la section Let's talk!

It does not solve the problem, could it be a problem caused by the CheckButton class ?

Do not use multiple instances of Tk, use Toplevel instances.

Thank you very much, the multiple instances of Tk were the problem. However, I have another question : can I put the Toplevel instances in a different class ? Do I have to use inheritance ?  

everything is possible

Okay, thank you very much
